As you can see in the second graph of the 10w7s, when they are plugged in to the LFE outputs, they also drop off at ~120Hz. When plugged in to the LF/RF outputs, they seem to do well up to at least 200Hz.
I was thinking of using a MiniDSP to add these to my front mains so I can run them large. Using the mains (Revel Performa F52) down to ~250 or so then letting the 10w7s handle everything else below that. This should take the load off my mains.
Second option would be to split the 10w7s into separate boxes and use them as subs to even out the bass response. They would be small enough to put them along the side walls. I currently have the two 5400s co-located under the TV on the front wall (center), the Revel B15a at the center point of the rear wall. These are the only places that these subs will fit. I may be able to split the two 5400s on the front wall, but I'd have to pull the mains out a bit.
Will a balanced MiniDSP 2x4 be able to handle all 5 subs? Assuming I leave the 5400s co-Located in the center I assume that I can consider them a single channel. I am going to get the LG FP14000 clone to power them. I'm guessing I will need the 4Way Advanced plugin for this application or the 10x10 if I go with the 2x8.
If I go with using the 10w7s as MBM I will need a second MiniDSP. Is getting the 2x8 with the more powerful DSP be beneficial at all or will I be just as well served getting another balanced 2x4? The cost difference is negligible (including building a box for the 2x8) in the overall scheme of things.
All the hardware and plugin options are quite confusing to me. Haven't had a chance to read up on all the features and forums yet.
Been too busy with 16 hour work days and trying to somewhat finish the house remodel so that I can get a refi. As soon as I get time to breathe, I'll get more measurements of the complete system to see what will yield the best results.
